GULTIV'ATO 3-.

Application filed December 24, 1918.

To all whom it may concern:

Be it known that I, HENRY J. Hnmnn, a

- citizen of the United States of America,

and resident of Carroll, Carroll County,

Iowa, have invented a certain new and use ful Improvement in Cultivators, of whichthe following is a specification.-

My lnvention relates to improvements 1n cultivators.

One of the objects of my invention is theprovision of a cultivator in which connections are provided between the steering mechanlsm and the gang shifting devices, so

7 that the wheel of the forward truck of the cultivator may be angled so as to alter the direction of travel of the cultivator simultaneously with the lateral shifting of the cultivator gangs in the direction of the angling of the forward wheel, whereby the' Figure 1 is a partial side elevation of a cultivator embodying the features of my inventlon.

Fig. 2 is a vertical transverse sectiona I view of the cultivator.

Fig. 3 is a plan View partially in section of a portion of the cultivator. I have illustrated a cultivator of the tworowl" type, although my invention is applicable to a single-row cultivator. The

frame consists. essentially of an outside" frame member. 12 formed of a continuous piece of channel iron, and the rear frame bar 15 preferably consisting of an angle bar. Extending forwardly from-the member '15 are a pair of intermediate longitudinal braces 16 which, at their forward end, are secured to the forward portion of the frame.

Likewise, 1 extending transversely across the machine at a point ad acent to the rear ends of the frame, are a pair of frame "members 17', spaced a short distance apart. The supporting wheels 18 are mounted on lateral extensions of the stub axles 19, the inner ends of which axles 'ing wheel 29.

extend upwardly and slightly rearwardly,

being mounted at their upper ends in the framein any suitable manner. The for ward end of the frame is supported by the forward truck, provided with a pair of steering wheels 20, mounted on 'a transverse v axle 20 to the mid-point of which the bent rod 21 is secured. This rod is provided with a vertically extending portion journalled in a sleeve carried by the bracket 22 secured to the frame. 1 The upper end of this rod 21 is provided with a bevel gear 23, which meshes with a smaller bevel gear 24 on the forward end of the steering rod 25. This steering rod extends rearwardly, and mount ed near its rear end is j a gear 26 which meshes with a second gear 27 mounted upon the forward end of the second steering rod 28 which extends rearwardly at a slightly upward incline, as shown in Fig. 1, and being provided at its rear end with the steerlVith this construction, it will be readily seenthat by operating the steering wheel, the rotation thereof is trans ,mitted to the forward truck to angle the wheels 20.

The cultivator shovel gangs are carried by a pair of arch bars 30-30 as clearly shown in Fig. 2, the shovel gangs being pivotally supported in the usual manner to the horizontal-extensions of 'these two arch bars. bars 30+30 are adjustably secured together by means of a sleeve 31 which is adapted to slip over the inner ends of each of the arch bars, and being secured thereto by means of the pins 31, which are adapted to engage with oneof the cylindricalholes 31 in the ends of the arch bars. There are a plurality of these holes 31 in the end of each arch bar, and by reason of this pin-and-hole connection between the arch bars and sleeve, the arch barscan be The inner ends of these arch adjusted laterally to provide for varying widths between the two rows. By reason of this construction, the two arch bars in effect constitute a single adjustable double arch bar. This double arch bar is suitably supported by a plurality of suspension rods which are secured to suitable yokes 33 mounted upon the arch bars 3O30 These suspension rods 32 extend upwardly and forwardly and are connected at their upper ends to the frame. .Likewise, secured to each of the yokes 33 are a plurality of suspension rods 32 which extend ,-upwardly and rearwardly, being connected at their upper ends to the transverse frame bar 15. Any suitablemeans may be employed jfor raising and lowering the shovel gangs such as the hand lever 35, which may bet-connected to the gangs in a manner illustrated in the copendins app icati n o H- Kaupke, Serial No. 183,154, filed July 27, 1917, patented August-,9, :1921, 1 ,387,405 by -which constructioneither one or both of the shovel gangs on either side of the machine may be raised. As this feature of construction forms nopart of my present invention, I will not. describet-hesame in detail, but reference may :be had to .said co-pending application fora completetunderstanding of thesame. However, it is understood that any other meansmay be employed for raising and lowering :the gangs, as :far as my present invention is concerned.

In order to. enable the shovel.- gangs to i be .readily shifted laterally, the arch bars 30 -30 are supported by two forwardly extending pivotal ,links 36, the rear/ends of :these links being pivotally supported "by the transverse frame member 115, while the forward endsof the links are secured :tothe arches 31,0f the double :arch bar.

Extending from .an intermediate point of one ofthelinks 3.6is alOd 37,:the opposite end of -.which rod is connected to an .arm 38 on the rear end of the steering rod. 25. Likewise connected to an intermediatepoint ofthe link 36 is ;a .secondrod .39, theiinner end of. which is connected to the forward end of a pivoted-member 4Q. This-member is pivoted about ,the rpm .41.'to, the frame These foot; levers,as clearly shown lIl'I-Flg. :3, are ;provided. with foot-rests 44, and are pivotally mounted at 45 in a suitable bracketcarried by the @frame member ,15, and are-provided with upwardly extending extensions 46 which-engage with the lateral arms 42.

lVith this construction, the arm 40 may be ,tudinally to swing .the link '36 about its pivotal point, which movement causes laterva1 shifting of .the double arch bar 30 and the consequent lateral shifting of the shovel gangs. Similar simultaneous movement is likewise obtained throughthe operation of the foot-levers, as when one of the footlevers 42 is operated, it rocks the member 40 about its pivotal point, thereby moving the rod 39, ,long-itudinally, which in turn swings the link 36 about its pivotal point, and thus shifts the gangs laterally as before. [This movement of the link 36 isalso imparted to the rod 37, which rocks the arm 38to thereby rotate the steering rod 25,

thereby angling ,the wheels of the foretruck.

It Will thus beseen that Lhave devised a-pery efiicient form ofcultivator, and one in which the wheels of the fore-truck can be angled simultaneously with the ,lateral wSlllfillIlQ ,of the gangs, so that it ispossible tto always maintain the line of draft sub stantially parallel to the rows being cultivated, whereby it is possible to .moreeffectively follow the-rows be ng cultinated.

Furthermore, by having this steering move- ,ment controlledboth by the hand wheel and the-foot lever it is possible to. apply a very eli'ectivebperating power so that the operator of-the implement can more readily control this steering, operation.

.W-lnle l have illustrated and described Ione particular embodiment of my invention, it willbe understood that I do not wish to be limited to the exact construction shown and described, but that various changesand modifications willreadily sugygestithemselves to ,those skilled in the art with ut departing from the spirit and in- .tent of ,my invention. .member 15, andris provided with a-pair of lateral extensions i421which are adapted to 1 be engaged-by the upwardly extending: portions of two foot levers 43.
